+**NFR-A11Y-3 — Colour-independent status.** Built, and now asserted. The clipping readout pairs a
+marker that appears or disappears with a figure in words; the rating strip is a solid star against
+an outline in an achromatic palette; the pick/reject mark is a tick against a cross; the
+focus-peaking colour chips say "Red" and "Cyan" rather than showing swatches; and colour labels —
+the requirement's first named example — now have an interface built with a shape from the start:
+every mark carries its label's initial (R, Y, G, B, P) on its colour, and every chip, picker and the
+develop bar name the label in words.
 
-Two caveats, because the tag now says more than the evidence does. **Only the clipping clause has a
-test** — `a_clipping_figure_distinguishes_none_from_nearly_none`, which pins `<0.1%` apart from `0%`
-so the figure cannot contradict the lit marker beside it. The three Slint components are
-inspected-and-argued, not asserted, and nothing would fail if a future edit made a star differ only
-in tint. **And the requirement's first named example has no interface at all**: catalog colour
-labels are a nullable `label INTEGER` column on the versions table and are set and shown nowhere, so
-the clause about them is untestable rather than satisfied. That clause closes when the label UI is
-built, not before, and it should be built with a shape from the outset — which is the same argument
-as below, for doing this alongside NFR-A11Y-2 rather than after it.
+The clipping clause is pinned by `a_clipping_figure_distinguishes_none_from_nearly_none`. The other
+four are pinned by `ui/dr-ui/tests/status_is_not_colour_alone.rs`, which reads the markup and fails
+if a star, a flag or a label comes to differ in tint alone — if the glyph a state selects stops
+depending on the state, if two states select the same drawing, if two labels share a letter, or if
+the peaking chips stop being words. It is a structural check, not a perceptual one: it cannot say
+whether the letters are legible at 14px on a given screen, which is still a matter of looking.
